Hi,
I'm using rrdtool-1.2.23nb1 on several NetBSD servers (i386 3.1.1 and amd64
4.0_RCx) and on all servers I see weird crashes (=core dump) when generating
the "last 12 months" image if the time is 03:00 - 04:55.
During other times (05:00-24:00-02:55) I have no problems at all. Also I have
no problems generating the "last 24 hours"/"last 7 days"/"last 4 weeks" images
even if the time is between 03:00 and 04:55.
I'm living in Finland so my time zone is currently +3 hrs.
I put these in /etc/mk.conf
INSTALL_UNSTRIPPED=YES
CFLAGS+= -g -static
CXXFLAGS+= -g -static
LDFLAGS+= -g -static
and these in pkgsrc/databases/rrdtool/Makefile
CONFIGURE_ARGS+= --enable-debug
CFLAGS+= -static
and built a debug version. However, I couldn't make any sense from the gdb...

Anyone else having this kind of problems with rrdtool?
